The two may not be related. The 505 code is for the IAC motor in the intake of the engine. Most often the cause of cherry red exhaust manifolds is unburned fuel getting into the exhaust and burning there. This can be due a a bad spark plug, plug, wire or coil causing misfires resulting in unburned fuel being ejected into the exhaust stream. It could also be due to a cracked or broken intake or exhaust valve. This would result in low compression in a cylinder, causing a misfire and having the same result.

If it gets worse as you're turning right, but not left - Most definitely a wheel bearing on the right side. The right turn puts more stress on the right wheel - louder noise - turn left and release the stress - no noise. You can also lift the vehicle up on a jack and listen to the wheel and hear the bearing in the hub making noise.
